in combination with a hygienic, removable insole, the latter-being adaptable to variations in construction to suit the particular needs of the individual wearer-in cases where deformities of the foot waterp'rooflng, warmth or ventilation are of primary importance.

Another object and feature of this hygienic, removable insole is that the construction of the insole may be changed at any time to correct or relieve a new development or deformity of the foot without requiring a new shoe, the removable insole alone being reconstructed.

Another advantage made possible by the greater depth of the removable insole is ventilation by means of holes running completely through the insole. Although the applicant realizes that air holes are not a new idea for ventilating the foot, yet in the past the shallowness of the insoles has practically prevented their proper functioning, because of the absence of sufficient compressibility of the insole.

The invention consists of an improved shoe construction wherein a deep recess is provided on the inside of the shoe in the space adjacent the sole; in combination therewith a removable insole adapted to fit the deep recess and to be constructed and changed to meet the specific needs for foot comfort of the individual.

The novelty of the construction and its features will be fully understood by reference to the accompanying drawing, wherein similar numbers "refer to similar parts throughout the several views.

Figure 1 is a perspective view of the removable insole.

Figure 2 is a perspective view of a shoe, constructed to accommodate the removable insole, the toe of the shoe being shown cut away for the purpose of illustration.

Figure 3 .is a cross section of the insole.

Figure 1 is a perspective view showing the under side of the removable insole. The said insole comprises an upper layer of leather it which lies adjacent to the foot and a pad I! made up of layers of felt or other suitable material cut out on the contour l8 and suitably fastened to the layer of leather l6. Figure 3 illustrates a crosssection of the insole on line AA.of Fig. 1.

Figure 2 illustrates a shoe constructed so as to accommodate the removable insole; in the drawing the toe ,of theshoe has been cut oil in order to illustrate more plainly the construction. The contour ll of the insole shown in Fig. 1, coincides with the contour l9 formed by .the inner edge of The object of my invention is to provide a shoe the welt III, the upper ii and the cut-out inner sole I 2.

The shoe is constructed by sewing a welt l0 and an inner sole I2 to the upper l I by stitching, as shown at l3 such stitching being preferably inserted by hand by means of an awl; the inner sole is thencut out-on a line l9 coinciding with the internal edge of the upper and welt. An outer sole I4 is then sewed to the welt ID by stitching as represented at i 5. It will be observed that a deep recess is formed in the shoe adjacent to the contour i9, which can be varied in depth by employing an inner sole l2 of greater or lesser thickness, as desired. The removable insole showniin' Fig. 1 is then constructed so that the pad I! is; adapted to fit within the recess in the shoe adijacent to the contour l9. 1

Due to the deep recess construction of the shoe, permitting a thicker removable insole, it is possible to construct the insole with greater variations in its surfacecontour to correspond to the deformities or unnatural protrusions of the foot, thus supporting the foot by convexing the surface of the insole at points needing support or concaving the surface at points wherepressure on the foot-should be relieved for comfort. This can be simply accomplished by reducing or increasing the number of layers of felt or other material at any particular point thus changing the surface contour of the leather layer l6 of the removable insole to correspond to the natural contour of the foot.

When ventilation is to be the paramount consideration in the construction of a shoe and removable insole, it is fundamentally accomplished by air-holes running completely through the insole as shown at 20 in Fig. 1; the amount of ventilation obtained is directly proportionate to the change in volume of said air holes through the compressibility of the removable insole. By constructing a shoe and removable insole as above described, the pad I! can be made of a greater depth than an ordinary insole and thus obtain the amount of compressibility desired. I

To reduce the transfer of dampness or temperature from outside through the sole of the shoe to the foot, the type of material making up the pad I! may be varied according to its insulating or waterproofing qualities.

Another limited application of my invention which I anticipate, is that although the insoleshown covers the entire area of the sole of the shoe, it may be desirable to confine it to the heel condition, the only change in construction necessary being the reduction in the area cut out of the inner sole l2, and then making the removable insole correspond to and fit the area cut away.

I claim:

A method of constructing a shoe in combination with a hygienic removable insole by sewing an inner sole to the upper and welt, removing any portion of the inner sole bordered by the 10 welt and upper, sewing an outersole to said welt,

said parts forming a pocket bottoming on the inner surface of the outer sole; providing a. removable insole having a pad of several layers of resilient material, corresponding in depth and area to the aforesaid pocket afiixed to a leather insole having a periphery coinciding with the periphery of the aforesaid inner sole; and inserting said pad in said pocket substantially as described.
